2Assignment 4TRU Open Learningb.Determine the significance of the correlation at α .05, two-tailed by referring to Table B.6in the Appendix of your textbook. State whether the correlation is significant.No. of Hours of StudyTest Score88410907856715734689861292670880Question 3 The educational psychologist in Question 2 above wanted to confirm the Pearson correlation that he obtained by ranking the number of hours of study and the test scores. He then computed the Spearman correlation. Using the data in Question 2 above:A) Do as the psychologist did ,and B) show whether his conclusion regarding the significance of the Spearman correlation is similar to his conclusion regarding the Pearson correlation. (After computing the Spearman correlation, refer to Table B.7in the Appendix of your textbook.)

Convert these data into a form suitable for the point-biserial correlation, and assign a score of 0 to the non-coffee drinkers and a 1 to the coffee drinkers. A) Compute the point biserial correlation ),and B) compute the coefficient of determination (r2) and describe how much of the variability in marathon speed is determined by its association with drinking coffee.
